PLUM. LRAVES. 
circular lid, the moth coming from it the following July. This 
moth is most readily distinguished by the fine prostrate curled 
hairs covering its fore wings and arranged in regular waves run¬ 
ning as it were from the base to the tip. Its body and legs are 
also very hairy and at the tip of the abdomen is a tuft of long 
soft hairs forming a bushy tail. It is of a straw yellow color 
with the fore wings more or less dusky on the outer margin, and 
the feet and orbits of the eyes black. The fore legs are often 
black on their anterior side and sometimes the face is also black. 
Width 1.20 to 1.80. I have never met with this in New-York 
and it is omitted in the second edition of Dr. Harris’s Treatise, 
but it appears to be common at the south and west. The Spar- 
shalli of Mr. Curtis can scarcely be distinct from this somewhat 
variable species, and I suspect Mr. Stephens (List Brit. Mus.) is 
in error in giving that as an Australian insect and that Boisduval 
was correct in regarding it as North American. Mr. Westwood’s 
generic name Trichetra was published the year before Dr. Harris’s 
name Lagoa.
